Can @peachbitcoin still be nonkyc given you have to download from the App Store? Or is it because you don’t need at ID to buy?

You can restore your account with a key so you not tying it to an email, but I guess if they store the accounts it could be matched to say apple or google Ids i'm not sure But as for buying you pick the payment option you prefer, they only escrow the bitcoin side of the trade kinda like paxful does
